This presentation concerns the stability of radicals generated in poly(ethylene-alt-tetrafluoroethylene) (ETFE) film by electron irradiation prior to grafting of styrene onto this base material. It has been demonstrated that the grafting yield decreases as the storage time of the irradiated film increases, and by ESR this has been shown to be due to decay of the polymerization-initiating radicals in the film material. The decay rate is found to depend on the storage temperature, and it may also depend on the type of radicals present in the film. Furthermore the conducted investigations have shown that the radicals are almost entirely consumed in the grafting process.
